Mitch True is the school reporter. He is overweight and decidedly non-athletic. He is the protagonist in this novel.
Angel Marichal is the miraculous football player (cornerback) that magically appears one day. His obvious talent has not even begun to shine on the field and Coach McNulty seems bent on keeping it that way. He seems to have no past (including records).
Coach McNulty. Typical coach, but add to that the fact that he's hiding a major secret about Angel.
